Preventative Maintenance
The following recommendations will help your system achieve maximum
efficiency in RO water production.
1. Filter maintenance
a. Filters may be stored for several years.
b. Place the sealed unopened filter in an airtight container to
prolong its shelf life and prevent it from absorbing unwanted
odors.
2. Membrane maintenance
a. The dry-packed membrane typically has a two-year shelf life. To
prolong the shelf life, keep the unopened dry membrane in the
refrigerator.
b. Once used, run the RO system every day for at least 10–15
minutes (about one gallon or four liters of drinking water) to help
maintain the membrane's performance.
c. If you will not be using the RO system for several weeks, drain
the storage tank completely. Fill the tank and drain it twice before
using the RO system again.
3. Filter and membrane change procedures
NOTE: THIS RO SYSTEM CONTAINS FILTERS THAT MUST BE
REPLACED AT REGULAR INTERVALS IN ORDER TO MAINTAIN PROPER
PERFORMANCE. USE ONLY FACTORY-APPROVED FILTERS.
Please see Page 4 for the recommended intervals for changing the filters.
Local water conditions and quality may dictate more frequent changes.
Use a drip pan to catch any water that may spill when the filter housing is
removed.
a. Shut off the water supply.
b. Turn off the tank ball valve by turning it 90 degrees.
c. Turn on the RO faucet for continued water flow.
d. Lift the filter housing up 1 inch and slide the housing wrench in.
Use one hand to hold the system and the other hand to turn the
wrench clockwise (viewing from the top) to open the housing.
